I started on one of my summer to do projects yesterday. The north side of my roof is pretty mossed up. The south side looks fine.
Since the roof is older, I decided no to power wash it and hopefully extend the roof's life a bit.
The moss is really dry and easily comes off with a very light scraping.
I figure about five hours time to get most of it off.
Once I remove, I like to treat it as I know I can't get every bit of it and it will come back.
Any suggestions on what to treat a composition roof from the PP moss experts?
I've heard Powder Tide, 50 /50 beach water....
Thanks for your input.
